Side-scroller

A side-scroller is a type of game where the player observes on-screen a flat cross-section of game events. Typically, the game itself is two- or two-and-a-half-dimensional. Most side-scrolling games have the player controlled sprite on the left, making their way to the end of the level on the very right side of the screen. The side-scrolling format was popular among platformers, side-scrolling shooters, and beat 'em upfighting games
